Plug connections should be blown dry with clean dry air (low pressure) and protected with
acid-
free Silicone grease Type “NOVA G624” or similar after drying. Always recharge the
hand held radio after use.
Although the connector arrangement is a waterproof type, under certain circumstances it is
possible for water to seep between the plug and the socket, causing undesirable
interference. This may be avoided by liberal application of silicone grease.
Do not carry the radio by the helmet/headset connecting lead.
Do not try to disconnect the helmet/headset connector by snatching or pulling the lead.
The radio should be secured to the vest or pocket by means of a lanyard connected to the
dedicated lanyard ring on the radio back plate.
If the MP20 is not operating normally, check indicator lights and channel settings. Check also
connectors for proper attachment.
A malfunction may also be corrected by switching the system OFF for a few seconds and
then ON again.
If you have trouble making the MP20 operate and before declaring the unit unserviceable, it
is recommended to go through the reset procedure found in
the document “AX-SVS-PRC-
0002 Reset Procedure
”. This procedure will restore the unit to factory defaults and possibly
clear any setting made accidentally, causing the unit not to operate properly. The reset
document can be downloaded from:
